Application filed July 21, 1915. Serial No. 41,049.

To all whomit may concern 1 Be it known that I, FRED VANGELIN, a citizen of the United States, and a resident of the borough of,Brooklyn, in the county of Kings and State of New York,-have invented certain new and useful Improve: ments, in Gas-Cocks, of which the following is a specification. 1

This invention relates-to safety gas-cocks which when closed are locked against accidental turning.

The object of the invention is to provide a cock of. this character whichhas. the apparent simplicity of an ordinarygas-cock avoiding complexity of construction and unsightly projections I,

'-This valve casing has on its, interior a conical valve seat and holes 1d opening from said pipe through said seat: The casing is provided adjacent. the largerend of said valve seat with a notch ornotches 25. A-conical valve 10 is disposed in said casing 11 fitting the seat thereof. This valve is provided with a transverse hole 13 adapted to regis-.-

ter with the holes 14 in said casing. This conical valve has a screw threaded -socket at its small end and an elongated angular stem 18 projecting from its large end. This stem has at its outer end an enlargement 22. A washer 15 rests on one end of the valve casing 11 anda screw 16 passes through said washer and takes into the socket at the small end of the valve 10. A key 19 has an angular passage 20 which engages the angular.

gage the notches 25 when the keyis turned off. I An expansive spring-23is disposed in the-recess 21 betweenthe .innerend thereof and the enlargement 22 atthe outer end of the valve stem and tendsEtohold' the keyin contact with the notched end of the-valve casing and to force the lugs 2l;into-engagement with the notches 25. when thecock is turned off, thereby locking the cock in closed position. 1 2 1.

Vhen it is. desired to turnion the gas, the key 19'is' drawn downwardly? against the pressure of the gspring23-until the projections 24* are entirelyfreeiof the: notches 2-5, whereupon .the valve may be? turned ;into open :position. =1 \Vlientheizvalve is {to j be closed the stem is turned until the .wprojec tions move EintQEthe notchesrQTn-by forcecof tliesspringi 17. whereupon further movement 273inxtlie iisu-a'lana'nnenn v k I ;:='It 'villvbesseena-that inthis'gava; anyrdana ger aloe to: iacci-deiital 1 opening of-itlhe valve, as. fiifltl l E the I old forms; of gas. cocks-g is en. til-cl prevented; and at: the same times the construction has ;1the-same neatiappearance of; thehordinary gas cook-.

"I claim: I A safety gas cook comprising a valve casing having a conical valveseat and a notch adjacent to the large end thereof. a conical valve turnablc in said seat and having at its small end holding means engaging said "alve casingat the smallendof said valve seat and at 1ts large end an elongated angular stein provided witha stop, a key having a lug adapted to engage said notch andtpro vided avith an angular passage along its inner portion engaging said angular stun ",2 being in' inverted-a position; and

and an enlarged recess in its outer portion in alineinent with said angular passage, and a spring disposed in. said recess between the inner end thereof and said stop, said holding means being operative to hold said valve to its seat independent of said spring and said sprin being operative to automatically lock said liey to said valve casing when the valve is closed and permitting a disengagement of the key from the casing for turning 10 the valve.

In testimony that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.
